Reserved

Valid with SMF70SRL ≥ X'5B'(91).

3 3 R7024MT 1 binary Reserved for diagnostic purposes.
4 4 R7024EN 4 binary Number of engines on the Crypto accelerator card. Specifies the number of valid entries in the R7024TC array.
8 8 R7024SF 8 floating Scaling factor for this cryptographic accelerator. Execution times in this data section have to be multiplied by this scaling factor to achieve a value in seconds.
The following block of data (R7024TC) exists five times for up to five engines of a cryptographic accelerator. Unused blocks are allocated with values set to 0.
16 10 R7021MET 8 floating Execution time for all operations in 1024-bit-ME format.
24 18 R7021MEC 8 floating Number of all operations in 1024-bit-ME format.
32 20 R7022MET 8 floating Execution time for all operations in 2048-bit-ME format.
40 28 R7022MEC 8 floating Number of all operations in 2048-bit-ME format.
48 30 R7021CRT 8 floating Execution time for all operations in 1024-bit-CRT format.
56 38 R7021CRC 8 floating Number of all operations in 1024-bit-CRT format.
64 40 R7022CRT 8 floating Execution time for all operations in 2048-bit-CRT format.
72 48 R7022CRC 8 floating Number of all operations in 2048-bit-CRT format.
End of five instances of the R7024TC data block.
336 150 R7023MET 8 floating Execution time for all operations in 4096-bit ME-format.
344 158 R7023MEC 8 floating Number of all operations in 4096-bit ME-format.
352 160 R7023CRT 8 floating Execution time for all operations in 4096-bit CRT-format.
360 168 R7023CRC 8 floating Number of all operations in 4096-bit CRT-format.
